LACING HOOK OR STUD.

SPECIFICATION forming part of Letters Patent No. 365,822, dated July 5, 1887. Application tiled February 26, 1887. Serial No. 229,064. (No model.)

To all whom it may concern:

Be it known that I, HUGH A. KINGsLAND, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Laeing Hooks or Studs; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to lacing hooks or studs, but is also applicable to buttons, where they are held in place by clamping plates or disks.

Heretofore both but-tons and lacing hooks or studs have been provided with disks adapted to be clam pednpon both sides of the material to which they were secured, the lower disk being formed with a depending tongue or projection bent at an angle to the plane of the disk, this projection serving as a screw-point, entering an opening made in the material, which is enlarged by the periphery of the disk until the whole disk has passed through and the material is held between the two disks. The depending tongue or projection is then bent down upon the material and the stud or button is thus securely clamped in place. This projection has been formed heretofore by slitting the lower disk on a straight line on one side of the center, from the periphery to within a third of the diameter from the opposite side of the periphery, or, in other words, to such an extent as would leave an amount of stock between the end of the slit and the periphery consistent with strength. As fastening devices of this character, however, are comparatively small, it has been found that the prong or depending projection was not of a length sufficient to extend through some of the material upon which it was desired to use the fastening-namely, when used on shoesand that it could not be made longer without weakening it and rendering it liable to be broken off in use.

The object of the present invention is to obviate this difficulty and so slit the disk as to provide a prong sufficiently long for all pur poses without in any way increasing the size of the disk or impairing the strength of the prong at its point of connection with the disk.

In the drawings, Figure 1 represents the invention as applied to a lacing hook or stud, and Fig. 2 represents the stud in place within the material, as it appears before the prong is bent up into place. Fig. 3 is a plan vicwofthc lower disk with the prong formed therein.

While I have shown and will describe the invention in connection with a lacing stud or hook, it will be understood that I do not limit myself in this connection, as a button having the same arrangement of clampingdisks may also contain the particular feature which constitutes my invention.

. In the drawings the head of the stud or 'hook, which is of ordinary construction, is

shown at a, being united with the disk I) by an eccentric neck, 0. The disk I) is united to a lower disk, (I, by a central post, a, and be tween the disks 1) and d the material is held to which the fastener is to be applied.

Instead of, as heretofore, slitting the lower disk on a straight line to one side of the ecu-- ter, I form a slit on a curve, which has its be ginning .on the periphery approximately on a line with the center of the post 6, extending outward on a slight curve and inward, bordering the periphery of the post to the rear thereof on a curve struck from a center on the opposite side of the post, thus providing a long prong, f, which, when bent up at an angle to the plane of the disk, serves particularly well as a screw-point to center the material, by reason of its curved inner face.

I do not desire to have .it understood that the disk must be cut precisely as indicated, the main feature being to form the slit on a curve, so as to get greater length of prong and at the same time refrain from weakening its connection with the disk by too near approach to the opposite periphery.

The use or application of thefastening is obvious. An opening is made in the leather or other material, the point of the prong inserted and-the stud turned, causing the whole lowerdiskto pass through the material, and the pro-ngIis-then forced down and the material thus securely clamped between the two Ljanraware that buttons have heretofore been madewith a slitted base-plate adapted to act as a screw for insertion into a garment in connection with a spiral twist or thread on the post, and I do not broadly claim this.

I claim as my invention- A fastening device for lacing books or studs, buttons, and the like, consisting of the parallel disks 1) and d, adapted to clamp the ma terial, and the prongf, formed by slitting the disk (I on a curve extending to and beyond the 10 post, said curve being struck from a center upon the opposite side of the post, substantially as described.
